SPECIFICATION forming part of Letters Patent No. 454,863, dated .Tune 30, 1891. Application filed November 8, 1890. Serial No. 370,761. (No model.)

To @ZZ whom. t may concern:

Be it known that I, JOHN M. GOODWIN, a citizen of theUnited States,residing at Sharpsville, in the county of Mercer and `State of Pennsylvania, have invented certain new and useful Improvements in Dumping-Cars, of which the following is a specification, reference being had to the drawings accompanying the same and forming a part thereof.

My invention relates to dumping-cars of that species in which the load is discharged or dumped without any careening or tipping of the car-body. a

The vobjects of my present invention are to provide a car which, without any careening or tipping of the car-body and without lany interference of the dumping apparatus with the running-gear of the car or with the track on which the car travels, will discharge its entire load of dumpable material, irst,out ward from the car, outside the running-gear and on either side of the car, or, second, downward and inside the lower frame of the car, and thence between the track-rails.

My invention consists in the combination, in a non-careening dumping-car, of fixed sides, a tilting floor, and valves hinged to the fixed sides and adapted to be supported at theirA lower ends upon said tilting floor.

It also consists in the combination, in a noncareening dumping-car, of fixed sides, valves hinged thereto, and a tilting fioor having segment-shaped brackets secured to its under side, with concave curved tracks secured to outward over said fixed discharge-floors or downward between the sill of the car.

lt also consists in the details of construction of the various parts and the combinations and sub-combinations thereof, which are hereinafter described, and definitely pointed out in the claims.

Referring now to the drawings, Figurel is an end View of the car embodying my invention.` Fig. 2 is a vertical sectional View on the line 2 2 of Fig. 4., the view being from the en d of the car which is shown in Fig. 4. This l view is intended to show the position of the parts when the car is dumping its load at one side. Fig. 3 is a similar view of the car, designed to show the position of the parts when the car is dumping its load downward between the sills of the car and thence between the track-rails. Fig. e is a side view of-one end of the car, the tilting door and its supporting-tracks being shown in vertical sections. Fig. 5 is a transverse sectional view of the tilting table at the point indicated on the line 2 2, the view being from the opposite 4 end of the car to that which is shown in Fig. 2. Fig. 6 is a central vertical section through a part of the tilting table and one of the segment-shaped brackets secured to the under side thereof. Fig. 7 is a vertical sectional view of one ofthe fixed inclined upper floorsections, the valve hinged thereto, and the hinging devices. Fig. S is a similar view to that shown in Fig. 5, showing another form of mechanism for operating the tilting floor. Fig. 9 is a side view showing the connection between the hinged valve and the iixed part of the car.

So far as dumping mechanism is concerned,

the ends of the cars are preferably substantially alike, whereby the tilting floor, the valves, and hinged discharge-door sections may be operated equally well from either end of the car.

Referring now to the parts by letters, S S represent the main sills, and T T represent trusses extending across thecar between-the main sills. Upon these trusses are secured the concave curved tracks, which support the tilting floor, and the trusses on both sides of said track pit-ch downward and outward, substantially as shown.

The tilting floor A extends lengthwise of the ear, and when the car is in condition to retain the load the upper side is substantially horizontal. To its under side are secured the segment-shaped brackets a. In a four-wheel car four of these brackets are sui'licient toafford the floor A a rin support.

IOS

cured to the trusses T T are the concave curved tracks C C. Friction-wheels h, mounted in the brackets a, having each a V-shaped groove in its rim, rest upon said tracks, whereby the tilting door is made to move easily and is guided in its tilting movements.

H H represent the top sides of the car. In the construction shown in the drawings each end of each top side is supported by a metal bracket, as h, which is fixed to the corresponding corner part of the car.

Upon the inboard face of each top side brackets d d are planted. The plates of these brackets extend entirely or almost entirely across the inboard face of the top side, and,

being bolted to the top side, serve to combine the members thereof and to stiften the top side. On the top flanges of the brackets d d an upper inclined floor D, extending the entire length of the car, is fixed. The vertical web of each bracket d, appropriately re-enforced locally by a boss, is perforated to admit the pivot of each pair of hinging-links B B. In the construction illustrated in the drawings it is intended to employ on each side of the car four pairs of these hinging-links. The lower ends of these hinging-links are connected by pivot-pins with a bracket g, secured to the under side of the upper edge of the associated valve G. These valves G G extend the entire length of the car, and they v may be made of planks lying edge to edge (load in the car.

and combined as a valve by cleats, and they may be lfaced with metal o1' made wholly of metal. The lower edges of the valves are supported on the tilting floorA when the several parts of the car are'in place to retain the The upper edge of each valve G is prevented from swinging down while its lower edge is resting on the tilting floor A by the flange g on the bracket g, which lies above the links B B and engages with them when said links and valve have moved to the position indicated by the dotted lines in Fig. l. Each of the main sills S S is beveled from near its upper inner edge downward and outward, as shown. Supported by each sill thus beveled and by several brackets secured thereto and having the same pitch is a fixed inclined discharge-Hoor F.

Secured to the several trusses T T on eaclr side of the car are brackets, in which are the bearings of a rock-shaft e.

F. E represent movable discharge-floor sections extending the entire length of the car, one on each side thereof, which are rigidly connected with the rock shaft e by the wrought-iron straps c. The location of the rock-shaft, the proportionate width of these movable discharge-door sections, the proportions of the straps, and the manner in which they are connected with the discharge-floor sections are substantially such as the drawings show, whereby when the discharge-floor sections are swung inward they will be supported by the inclined upper sides of the trusses T T and in position where they will form a continuation of the tilting floor when the car is discharging its load at the side, as shown in Fig. 2. When swung outward, they are stopped and held bytheir engagement with the fixed discharge-doors F. gagement of the lugs e2 of the strap c with small brackets t, secured to the trusses T, also contributes to preventing the said dischargefloor sections from falling outward beyond the position shown at the left in Fig. 3. The ends of the rock -shaft eextendl through the ends of the car, and a lever e3 is secured to each end of said rock-shaft, whereby the same may be rocked to move the discharge-Hoor sections to either of their two operative positions, as shown.

Secured to the intermediate sills of the car are the pedestal-brackets I I, arranged at suitable intervals. A shaft J, extending preferably the entire length of the car and through both ends thereof, so that it can be operated from either or both ends, is mounted in these brackets, and suitable connecting mechanism between this shaft and the tilting door is provided, whereby the floor may be tilted by the revolution of the shaft.

The preferred connecting mechanism between the shaft and tilting ioor is shown in Figs. 4 and 5, wherein two spools il il are shown keyed to said shaft J. Secured to these spools and oppositely wound upon them a're the two cables or chains K K', which pass each under one of the loosely-mounted sheaves L L and thence to points nearthe outer edges of the tilting fioor, to which said cables are attached, as shown clearly in Fig. 5. The sheaves L L are mounted on pedestal-brackets secured to the intermediate sills.

The mechanism shown in Fig. 7 includes a pinion M, keyed to the shaft J, and two pinions N N', secured to an independent short shaft n, which is mounted in a pedestalbracket secured to the intermediate sills. The pinion N meshes with the pinion M, and the pinion N meshes with a concave segmentrack O, which is rigidly secured to one of the curved brackets a.

Secured to each end of the shaft J outside of the end bulk-head of the car, are the means provided for revolvingsaid shaft. v The means shown consist of the wheel P, keyed to the shaft and having at intervals near its edge the pins p. This wheel, and consequently the shaft J, to which it is attached, may be revolved by means of any sort of a lever which may be inserted between the pins p. A ratchet-wheel p', keyed to the shaft J or secured to or made a part of the wheel P, is adapted to be engaged by a pawl p2, pivoted to the end bulk-head. The ratchetwheel teeth are of like pitch on both sides, so that the pawl may be swungaround in such manner that it will permit the shaft J to be revolved in either direction desired, but will prevent the revolution in the opposite direc tion. There being one of these ratchet-andpawl connections at each end of the shaft J,

The enl IOO IIO

'one pawl may be swung around so that by engaging with Vits ratchet it will prevent the revolution of the shaft in one direction, while the other pawl may be arranged to prevent the revolution of the shaft in the opposite direction. Consequently the tilting. floor is held in its horizontal position. This will be 'Jthe position of the parts and their mode of operation when the car is in a position to be loaded.

All parts of the car being in a position substantially as shown in Fig. l by the dotted lines, the car is in readiness to be loaded. Now when it is desired to dump the contained load 4upon either side-say, for example, upon the ,left side of the car, asit is shown in Figs. l and 2-the movable discharge-floor section E is swung to the position shown in Fig 2- that is to say, resting upon the trusses T, v(if it was not previously in that position.) The shaft J is then revolved by a suitable lever engaging with the pins in the wheel P until the floor A, moving in its concave curved supporting-track, reaches the position shown in Fig. 2. In assuming this position it is withdrawn from beneath the edge of the hinged valve G on the left side of the car, which valve swings outward by gravity to substantially the position shown in Fig. 2. The fixed inclined oor D and the hinged valve G on one side of the car and the tiltingfloor and the movable discharge-floor section E and the fixed inclined discharge-floor section F on the opposite side of the car will thus form a substantially continuous inclined surface extending across the car and throughout the whole length of the same, along which the load will slide, following the valve outward, and be discharged outside of the car and without touching the running-gear.

Assuming the parts again in the position shown in Fig. l and the car to be loaded, if it is desired to discharge the contents between the track-rails one of the-movable floorsections E, as that shown at the left of Fig. 3, is thrown outward to the position shown. The tilting iioor is then moved, as before described, to the position shown in Fig. 3. In reaching this position the hinged valve on the side on which the tilting door is depressed is released and swings outward until it engages with the movable discharge-floor section, as shown. The load in the car will be discharged through the space between the lower edge of the tilting floor and the partition'formed by the floor-section E and valve G, and thence between the track-rails, orboth movable floorsections E E may primarily be thrown outward, and after the valve G has been, as aforesaid, released the tilting floor may be reversely tilted and the other valve G also released, whereupon a part of the load will be discharged downward between the tilting floor and the movable fioor E.

`W'hen 'it is desired to return the hinged valve to the position where the car may be loaded, as shown in Fig. l, a hook r upon the end ofthe chain R is drawn downward until said hook is hooked into a staple g2, secured to the lower inner side of the valve G. The other end of the chain R is secured to the shaft XV, extending lengthwise of the car and upon which may be iitted a crank-key for the purpose of revolving the shaft and thus winding the chain thereon and drawing the valve to substantially the position'in which it is shown in Fig. l. The tilting floor is then allowed to return to its horizontal position and the car is again ready to be loaded.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is l l.
